Hello,
compared to v1 (Message-Id:
20210114151630.128830-1-u.kleine-koenig@pengutronix.de) I did the following changes:
- add "serial" to the summary line of the patch removing the serial
driver
- actually remove the serial driver in the patch that claims to do this
instead of patch 1.
On irc Arnd signalled to want to merge the first patch. As there are no
hard interdependencies between these, I think the best approach is for the
individual maintainers to pick up the patches they are responsible for.
Thanks and best regards,
Uwe

Support for this machine was just removed, so drop the now unused clk
driver, too.
